AI835 ch8 as cold junction
I am working on one project, the susyem is AC800M PM856 + AI835 for industrial frunace project.
If I use all 8 channels of AI835 as TC input, the error is about 5 degree, same for 3 boards, we used a gauge meter to simulate TC signals.
So I used Ch 8 as cold injunction, connected to one 4-wire PT100 RTD, connected as shown in the manual. but It doesn't work. Ch8 shown a triangle error, I dn't know what is wrong?
in the property tab, I set channel 1 to7 measured via channel 8, set ch 8 Pt100, -40~100. also has one variable connected to ch8.
